Center Director & Head Coach

Sachin Gore, Owner

Welcome, I'm Sachin!

In addition to teaching students math at Mathnasium, I am also a math teacher at Hill-Murray school in Maplewood, where I teach Algebra 1 and Algebra 2 to 8th-12 grade students.

While I am now a business owner and educator, my education and experience are actually in the field of engineering. I went to Penn State where I completed my Bachelor's and Master's degrees in Mechanical Engineering. I later completed my Masters in Business Administration (MBA) at Drexel University. If you haven't figured it out by now, I grew up in Pennsylvania near Philadelphia!

I love teaching kids math because I feel math is such an important life skill and I know that many students find math to be frustrating and confusing. Using math to solve engineering and business problems was key to success in my own career. While math came relatively easy to me, my son, now in 11th grade, struggled to "get" math and I struggled to teach it to him in a way that made sense until we discovered Mathnasium!

During my engineering career, I worked at Ford Motor Company in Dearborn, Michigan for a few years before moving to Minnesota to work at Andersen Windows in Bayport for 17 years. During that time, I had the opportunity to help start up a new factory, improve existing products and develop new products.

In addition to living and working in the St. Croix Valley with my wife and son, I enjoy teaching personal finance, business, and entrepreneurship in K-12 classrooms as a Junior Achievement volunteer. I am also on the board of the St. Croix Valley Athletic Association (SCVAA) and mentor high school students through Rotary's STRIVE (Students Taking Renewed Interest in the Value of Education) program.

Math Assistant CoachAlex Mondragon, Center Director

Hi there! I’m Alex, I have a bachelor’s degree in Elementary education with an emphasis in math and science from the University of St. Thomas.

I am a dedicated life-long learner. I love to encourage our younger generation to be excited and engaged in learning.  I love to share my passion for math with all of my students. The thing I love the most about teaching math is watching the growth in confidence in every child with their math skills. Students excitement about learning is the most rewarding thing as an educator.

I’m from Colorado and moved to Saint Paul, Minnesota in 2010 to attend the University of St. Thomas.  After college, I was an early childhood educator in Saint Paul for 5 years. I worked with a variety of ages groups, but spent most of my time with toddlers, and preschool students.  More recently, I had been working as a restaurant manager in Saint Paul. In my free time, I enjoy baking, crafting, and photography. I enjoy visiting state parks, hiking and kayaking during the warmer months. 

Math Assistant CoachAmanda Hannasch, Lead Instructor

Hi there, I’m Amanda!

I love being able to work with students and helping them succeed, in both math and life.  My favorite part about teaching math is seeing the “light bulb” moment; the moment that they finally understand the concepts that they are working on, and then being able to breeze through their work.  It’s very rewarding to be able to be a part of that success!

I grew up in Lake Elmo, Minnesota, and am an alumnus of Stillwater Area High School. I recently graduated from the University of Wisconsin-River Falls with my Bachelor's of Science in Mathematics. In addition to my studies and job, I love to volunteer through Junior Achievement (JA) and Strive Mentoring.  I also love reading, being outside when it's warm out, and spending time with my German Shepard mix puppy!

Math Assistant CoachShad Vork, Senior Math Coach

Hi, I’m Shad. I have a bachelor's degree in Chemistry with a minor in Mathematics.

I tutored math throughout college but went in an altogether different direction for a career. In the past few years, I tutored a couple of family members in high school math and ACT prep. Through this time, I remembered how much I love math as well as seeing others learn it.

My other interests include playing trombone with Stillwater’s Valley Concert Winds, playing games with my family and studying the Bible.

Math Assistant CoachDan Geister, Senior Math Coach

Hi!  I’m Dan and I am from River Falls, Wisconsin. I have a bachelor's degree in Geology.

I have been working in education since 2005 and at Rutherford Elementary in Stillwater since 2015. I've been also teaching at Mathnasium since 2016.

Outside of teaching I have an abundance of interests. I am involved with the Pierce County Historical Association and have a major interest in local history. This passion has led me to write two local history books. I also love Star Wars, consider myself an 80’s Music Enthusiast and Collector and I’m always on the hunt for old albums.

Math Assistant CoachRyan Ciminski, Math Coach

Hi there! My name is Ryan, and I am currently a freshman at the Illinois Institute of Technology majoring in Applied Mathematics and minoring in Computer Science. I grew up in Stillwater and graduated from Stillwater Area High School in 2020.

While attending IIT remotely this semester, I am an active member in the Machine Learning club, serve as a Fiance Board advisor for the IIT Student Government Association, and I am apart of the Discrete Mathematics focus group (we are currently researching tumor volume growth rates using logistic equations and computer programming.

While not solving for x, I love to listen to a good podcast, exercise, play the violin, and travel.

Math Assistant CoachMichael Fronczak, Math Coach

Hi, I'm Michael! I am a senior at Stillwater Area High School and am currently taking AP Calculus AB and AP Statistics. My favorite part about working at Mathnasim is getting to help students figure out problems they couldn't before.

In my spare time, I play varsity lacrosse, an din the winter I enjoy playing hockey with my friends. Along with Mathnasium, I also coach a youth lacrosse team. Lastly, I love spending time with family and friends, making new memories.

Math Assistant CoachLizzy Ward, Math Coach

Hi, I'm Lizzy and I am from Hudson, WI. I am a senior at Hudson High School Where I have taken math classes through pre-Calculus, including AP Statistics.

I chose to work at Mathnasium because I believe that having a strong understanding of mathematics has made every aspect of my life easier. I've always loved working with children and want to help students gain a lasting understanding of math.

Outside of Mathnasium, I am involved in several extra-curricular groups at Hudson High School. I love to cook, box, hike with dog, volunteer, and spend time with my friends.

Math Assistant CoachCeleste Nelson, Senior @Home Math Coach

Hi, I'm Celeste! I have a bachelor's degree in mathematics/secondary education and a master's degree in education. The past thirty years I have been working in the education field. Most of that time has been spent teaching middle school math and graduate level technology courses. Currently, I am the Math Interventionist for Hudson Middle School.

In 2018, I joined the Hudson Mathnasium in-center team. In the spring of 2020, I started working with Mathnasium@Home. I still do some instructing; however, my main responsibilities involve preparing the @Home classrooms and student materials. Two things I like the most about Mathnasium are the individualized learning plans and watching students develop their math skills.

Outside of work, I enjoy spending time with my son and our dog. I love to travel, read, craft, watch movies, scrapbook via Shutterfly, and complete Sudoku puzzles.

Math Assistant CoachPhilip Herder, Math Coach

I enjoy working with youth and helping them grow as individuals. Math was always my favorite subject growing up. The highest level of math I was able to do was Calculus and Statistics. I enjoy the challenge math offers and am ambitious to solve every problem.

My other interests include playing and watching sports, any activity outdoors, cooking, and spending time with my family and friends.

Math Assistant CoachGail Gerdts, Math Coach

Hi, I'm Gail. I am a retired teacher. I have taught preschool through 12th grade in all subjects the last 35 years. My most recent experience was 21 years at Hudson Middle School as a Special Education teacher, with a focus on Learning Disabilities.

Teaching at Mathnasium@Home has been a fantastic experience for me. It allows me to do what I love, while staying home. I enjoy helping students that are finding something to be a challenge. I so enjoy watching them be uplifted when they understand a concept. I had a student tell me, "At first it is hard, then I start to get it half way. Then, I understand and it is easy".

When I'm not teaching, I enjoy family time. I have three children, a daughter and boy-girl twins that are all in college. I also enjoy sewing, reading, and traveling when times allows.
